Mike Wilcock - Return Current IP Address - IT Professional, High Peak, UK.

This simple application uses several built in PHP functions to determine and then display the public IP address of the device that is being used to load the web page.

An example of the code is presented below:

// Return current IP address.
function getUserIP
{
    if(!empty($_SERVER['HTTP_CLIENT_IP']))
    { 
        //ip from share internet
        $ip = $_SERVER['HTTP_CLIENT_IP'];
    }
    elseif(!empty($_SERVER['HTTP_X_FORWARDED_FOR']))
    {   
        //ip pass from proxy
        $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
    }
    else
    {
        $ip = $_SERVER['REMOTE_ADDR'];
    }
}
return($ip);

// Return current IP address.

function getUserIP

{

if(!empty($_SERVER['HTTP_CLIENT_IP']))

{

//ip from share internet

$ip = $_SERVER['HTTP_CLIENT_IP'];

}

elseif(!empty($_SERVER['HTTP_X_FORWARDED_FOR']))

{

//ip pass from proxy

$ip = $_SERVER['HTTP_X_FORWARDED_FOR'];

}

else

{

$ip = $_SERVER['REMOTE_ADDR'];

}

return($ip);
